Manchester City put a smile back on Pep Guardiola's face as they swaggered into the FA Cup fourth round with a 5-0 demolition of West Ham on Friday.

Guardiola showed signs of feeling the strain of City's inconsistent season when he snapped at reporters during a series of tetchy interviews following Monday's win against Burnley.

The Spaniard was also forced to backtrack this week after appearing to suggest he wouldn't be in management much longer and seeming to admit City weren't as big a club as rivals Manchester United.

But the City manager's image issues looked a lot less problematic after his team destroyed West Ham with a three-goal blitz in the space of 10 minutes at the London Stadium.

Yaya Toure's penalty opened the floodgates before Havard Nordtveit's own goal and a David Silva strike effectively finished the third round tie before half-time.
